SILK-DRESSING MACE Application filed. April 1, 1926.

In the preparation of silk it has been customary in the past to arrange the fibre on sticks in a form commonly termed a fill or fills. These fills are mounted in what is commonly termed a cylinder which carries around its periphery a large number or" fills successively arranged. As the cylinder revolves the silk is combed by what is termed a card drum so that the fibres are straightened out and most of the foreign particles in the fills removed. The fills are srmported in the cylinder by sliders so that, of course, only one end of each fill is exposed for treatment. The exposed ends of the fills are first combed on one side and then on the other during one rotation of the cylinder. l Vhen the cylinder has completed one rotation the operator removes the fills turns them over and clamps them between the sliders, leaving the sticks attached to what are now the outer ends of the fills. These sticks then removed and what are then the outer ends of the fills are combed first on one side and then on the other. The sliders are arranged in groups so that when the carding is completed the fills of each group, when re leased from the cylinders, constitute what are called flags. These flags are removed from the cylinder by hand, tolded up and placed in a can or other receptacle in which they are taken to the picking department where they are inspected.

After having been inspected ant picked, the flags are runthrough a SPFGElCllllf" machine which draws out the fiaggs into what is termed a sliver. The silk which has been collected at the card roll according to the customary practice is stripped from the card rolls after a certain amount has been collect ed. The product of this roll is called a lap ano is usually tied in a knot. These knots are again put through the filling; machine :lor the formation of fills and treatment as before.

One object of my invention is to increase the production of machines of this character.

Another object is to automatically turn over the fills so as to eliminate the hand operation and its inaccuracies and also to simplify the operation so that the machine will not require the same degree of skill in its operation.

Serial No. 99,641.

Another object is to automatically strip the lap from the card drum.

Another object is to form a continuous sheet of laps and thus do away with the knottinp; and rehandling ot the material be fore it is filled.

Another obiect is to reduce the number of operatives required for a given production.

According to my invention ll provide special sliders adapted to support the usual fills. These sliders are mounted in a cylinder or drum and the fills with their sticks are inserted in the sliders by hand in the usual manner. The sliders are arranged in groups and. th fills are combed first in one direction and then in the other by a pair of card rolls. @ne card roll is larger tlian'the other and the carding from the smaller roll is automatically transferred to the larger roll. [lifter the outer ends of the fills have been combed the sliders are separated automatically and the free ends of the fills are drawn in between the sliders. Elie sticks are then released and discharged so as to expose what was the inner ends of the silk. This action corresponds to the usual hand turning; operation. The ends of the fills which have ust been released are then antomatically combed, first on one side and then on the other, by a pair of card rolls similar to those first mentioned. [litter the second end of each fill has been carded the groups 01" fills tor-mine; flags are removed and inspected and treated in the usual manner.

The opposite ends of the machine are provided withstripping; mechanism tor autoniiatically removing the laps from the card. rolls and winding them up into balls or rolls with strips of. canvas.

This pull out mechanism consists of a picker which is brought into action to grip the lap on the card roll and draw it out between two take oil aprons. One of these aprons is movable to clear the picker and the other apron carries the front end of the lap into a position to be gripped by another horizontal apron. These two horizontal aprons carry the lap to a strip of canvas which conveys the laps from the machine and winds them up in a ball or roll. Details of the construction by which the various parts are started and stopped from time to time as required will be understood from the following specification.

I will not attempt to describe in detail various constructional parts of a conventional nature or those details which will be within the knowledge or informatimi of the man familiar with this art, for l anticipate that many changes may be made in the construe tion and arrangement of the parts and that mechanical equivalents may be substituted for various mechanisms for performing the necessary essential operations.

The reference numeral 50 will be used to designate the frame of the machine urcept when some special form of construction is required. The main cylinder has two skeleton like discs 51 mounted on bushings 52 which are supported in the side frames of the machine. These discs 51 are connected by a series of headers 58 which have ends 56 are bolted to the rim of the discs as shown in Figs. 6 and 7. The sliders or clamping bars 5 1- and 55 are arranged in pairs and each slider has a projecting stud 56 which rests on the periphery of the disc 51 and 1s held in place by a band or ring 57, there being sufficient space between the band and the disc to permit the sliders to work freely. The sliders are constructed so as to provide a recess near the outer surface and nearer one edge than the other to receive and clamp the sticks 59 to which the fills of sills are attached. The discs 51, bands 57 and sliders 53 constitute the carrier for the sliders 54. and 5, which, in turn, carries the fills of silk. Each slider is also provided with a roller 60 on its outer end for co-action of the opening and separating mechanism which will be hereinafter ex:- plained. The operator who handles and inserts the fills and removes the stands on the platform 61 and leans against a support 62. A shelf 63 is usually provided for the sticks being handled.

The groups of sliders are yieldingly pressed together by tightencrs on opposite sides of the machine. Each tightener con sists of a lever 65 which is pivoted at. to one of the n'iain discs 51. This lever has three arms, one of which is adapted to press against the sliders, and the other two arms extend inwardly. A link 67 is hinged to one of the inner arms of the lever 65 and connected by a. tension spring 68 to the disc. This link 67 carries a roller 69 which is adapted to travel on a stationary cam 70. The two cams may be connected by a cross bar or tie 71 for reinforcing the same. A spring 72 is interposed between the movable end of the link 67 and the other arm of the lever 65 so that the spring 72tcnds to press the roller 9 against the cam '20. The inward movement of the link 6'? and the roller 69 is limited by alink 73. The pressiu'e of the spring 72 may be adjusted by a nut 74. A shoe 75 serves as an internal cam opposite one of the low spots of the cam 70 for engaging the rollers 69 as they pass upwardly (at the right of Fig. 7) so as to retract the pressure lever 65 from the sliders. As the dressing cylinder rotates left handed as viewed in Fig. C it will be seen that each roller (39 is forced outwardly as it reaches the high spots on the cam '70 so as to press the sliders together. in view of the fact that the total circumferential distance kept by the sliders of a group varies with the thickness and disposition of the fills I have provided the springs 72 which ensure a proper grip or cla -1 g action of the lever 65 and the same time allows for variations in thickness of the fills.

The driving of the main dressing cylinder may be effected in any suitable manner. For convenience and eiliciency l have provided a single source of power such as amotor for driving the principal parts of the machine including this main cylinder. The shaft of the motor 80 is connected by a belt to a pulley on tie shaft 81 as shown in 1 which shaft extends across to the o1. posite side of the machine. There is a ve tical shaft 82 on each side of the machine which is driven from the cross shaft 81 by spiral. gears sucl'i as 83 and 8%. A horizontal shaft 85 is lriven fron'i the verti'al shaft 82 by mez'zns of spiral gears 86 and 8?. A stud shaft 88 which is supported in the frame is driven from the shaft 85 by worm gears and 90. @n the inner end of the stud shaft 88 is a pinion 91 w 'ch meshes with an annular gear 92 on the outside of the cylinder disc 51. It will thus be seen that the main dressing cylinder or slider carrier is driven continuously by the application of power to the annular gears 92 on the opposite discs 51.

lhe fills are made up in the usual manner, consisting of sticks 55) having ends of the silk iibrc 101 w'apped around the-sticks. The outer ends are combed during the pars sage of the sliders and fills "rem the upper part of the carrier cylinder downv-xardly and toward the left, as viewed in Fig. 7, so that after the ends have been combed they will lie over-laltiping each other, as shown at 102 in Fig. 9.

The combing of the fills may be c'llectei'l by mechanism such as has been used in the past. I prefer, however, to use the special me anisnr which will be hereinafter des "ribed.

The automatic operation of the sliders for the purpose of reversing or turning over the fills is controlled from the transverse shaft 103 which has bearings in tle sleeves $2. This transverse shaft l has on it a spiral gear 10 i which n'le hes with another spiral gear 105 on slrii at the side of the meehinc. The opener 106 has its lower end beveled, as shown in Fi 9, so that it can be forced downwardly between the ends of two adjacent sliders, as shown in Fi 10,

to separate them. As the carrier cylinder .is rotating continuously, it is necessary to provide not 'only a vertical movement for the opener but a horizontal movement so that it may follow the rotation of the carriage. For this purpose the opener is secured to a slide which has a compound movement. This slide consists ot a horizontal frame 107 guided in bars 108 which slide on stationary guide-ways 109. The vertical movement or the opener is el'l'ected by a cam 110 and roller 111 carried by link 112, the lever 113 fixed to one end of shaft 114; and the slotted arm 115 which is lined to the inner end of the shaft 114 and engages the upper end or the opener bar 106. The cam 110 is shaped so as to oscillate the arm 115 and the opener bar 106 periodically as the pairs of sliders follow each other sequentially. The horizontal movement of the opener is effected through the cam 116, link 11?, and lever 118 similar to link 112 and lever 113. The lever 118 is secured to the outer end of the sleeve 110 which carries an arm 120 at its inner end. This arm 120 has a pin and slot connection with horizontal frame 107, as shown in Fig. 9. To permit of slight variations in the position of the opener 106 due to irregularities in the disposition to the sliders, T have constructed the opener 106 so that it is permitted a relative movement circumferentially with respect to the cylindrical carrier. This is effected by pivoting the lower part of the opener at 121 to the upper part or the opener. The lower part of the opener carries two spaced studs 122 at its upper end between which are mounted spring leaves 123 which are connected by the pin 1241 guided in a slot in the lower end of the upper part of the opener. The lower ends of the spring leaves 123 are secured or pressed against the pivot pin 121 thus permitting the lower end of the opener 106 to have a resilient action and yet normally being mounted in the definite posit-ion with respect to the carrier frame A transverse abutment bar 126 extends across the inside 01' the frame of the machine adjacent the lower part of the cylinder or carrier so as to bend over the outer ones of the fills as they pass over the abutment bar.

While the openers 106 on the opposite sides of the machine are holding adjacent sliders separated, as shown in Figs. 10 and 13, a turn-over member 130 is moved dow* wardly between the separated sliders into the position shown in Fig. 13, and then retracted so as to draw up the ends of the fills between the sliders, as shown at 131. This action or the turn-over member 130 is controlled by cams 132 and 1333. Cam 132 controls the vertical movement of the turn-over member and cam 133 controls the horizontal movement. The turn-over member is pivotally secured to the vertical bar 131 and normally held in tension by the spring 135. lar 13 1 is secured to horizontal frames 136 which are guided in the vertical slides 137 which slide on the guide-ways 137. The vertical action of the turning member is effected through the links 138, crank 139, and slotted arm 1410, the crank 139 and arm 1 10 being secured to the shaft 111. The hori zontal movement 01 the turning member is eliiecled by the cam 133 through the medium 01 the link 1 12, cranks 14:3, shaft 111, and crank 1 which is connected to the slotted member 116, secured to the frame The relative location 01" the sliders, the turn-over member 130, and the abutment 126 is such that as the slider carrier rotates, the turnover member 130 moves downwardly between the adjacent sliders, as shown in Fig. 13, the abutment member 126 bends over the outer ends of the fills 102., the turn-over member picks up the outer ends of the fills and draws them between the sliders as the slider carrier rotates. lVhen the opener 106 is retracted, the sliders are immediately forced together-by the action or the pressing levers 65. The spring 68 keeps tension on the pressing lever at all times and insures a proper gripping action 01" the sliders, notwithstanding variations in the thickness of the fills. The cross bar 141"? connects the lower ends of the guides 138 so as to hold them securely in place.

After the iills have been engaged as shown at 131, the sticks must now be released so as to free the opposite ends or the fills for subsequent treatment by suitable operating mechanism. This is accomplished by mecha -nism as shown in Figs. 1 and 17. The

opener member 150 is hinged to one end or the lever 151 and operated by a cam 152 through the medium of a link to the end of the lever 151. The opener 150 is hinged to the lever 151 and kept under the tension of a spring 15 1 so that the point of the opener as it' enters between the ends of the sliders may yield and follow the rotation of the slider carrier. A spring 155 afl'or ls a yielding abutment for the opener 150 so as to compensate for variations in the spacing of the sliders due to the thick ness ot-the iills. hen the sliders have been separated, as shown in Fig. 18, the stick is free to fall out. To insure unitorm di charge action, however, 1 provide the kickout lingers 156 on opposite sides or" the ma; chine to engage opposite ends or the sticks. These kick-out lingers are pivot-ed at 157 and operated by a link 158 and spring The rear end 01 the kick-out finger is slotted to permit relative free movement 01" the link 158 during a part 01? its vertical stroke, which is greater than that required for the action of the kick-out linger 11s soon as the openers 150 are retracted, the sliders are pushed together again in the manner 53 which is connected I
